Abstract
In a reciprocating drive device, for example, in a power window device for a vehicle, a drive member is reciprocated by transmitting a rotating force from a motor to a regulator. A driven gear of the regulator is engaged with a drive gear fixed outside a synthetic resin housing of the motor to an output shaft of the motor. In the reciprocating drive device, a relative movement between the housing of the motor and a support base to which the housing is attached with screws is surely prevented by a relative-movement preventing unit having an engagement structure between the support base and the housing.

A reciprocating drive device for reciprocating a drive member, comprising:
- a motor including an output shaft having a housing, and a drive gear disposed outside the housing to be rotatable integrally with the output shaft;
- a regulator having a driven gear meshing with the drive gear, the driven gear being operatively linked with the drive member;
- a support base for supporting the driven gear and for fixing the housing;
- a screw-fixing unit through which the housing is directly screwed to the support base;
- and
- a relative-movement preventing unit, being provided by an engagement between the support base and the housing, for preventing a relative movement between the support base and the housing.
